When CONFIG_PM_SLEEP is not set, there is a warning that
qcom_ipcc_pm_resume() is unused:
drivers/mailbox/qcom-ipcc.c:258:12: error: 'qcom_ipcc_pm_resume' defined but not used [-Werror=unused-function]
258 | static int qcom_ipcc_pm_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old
ones") reworked the PM_OPS macros to avoid this problem. Use
NOIRQ_SYSTEM_SLEEP_PM_OPS directly so that qcom_ipcc_pm_resume() always
appears to be used to the compiler, even though it will be dead code
eliminated in the !CONFIG_PM_SLEEP case.

The journal no-space deadlock was reported time to time. Such deadlock
can happen in the following situation.
When all journal buckets are fully filled by active jset with heavy
write I/O load, the cache set registration (after a reboot) will load
all active jsets and inserting them into the btree again (which is
called journal replay). If a journaled bkey is inserted into a btree
node and results btree node split, new journal request might be
triggered. For example, the btree grows one more level after the node
split, then the root node record in cache device super block will be
upgrade by bch_journal_meta() from bch_btree_set_root(). But there is no
space in journal buckets, the journal replay has to wait for new journal
bucket to be reclaimed after at least one journal bucket replayed. This
is one example that how the journal no-space deadlock happens.
The solution to avoid the deadlock is to reserve 1 journal bucket in
run time, and only permit the reserved journal bucket to be used during
cache set registration procedure for things like journal replay. Then
the journal space will never be fully filled, there is no chance for
journal no-space deadlock to happen anymore.
This patch adds a new member "bool do_reserve" in struct journal, it is
inititalized to 0 (false) when struct journal is allocated, and set to
1 (true) by bch_journal_space_reserve() when all initialization done in
run_cache_set(). In the run time when journal_reclaim() tries to
allocate a new journal bucket, free_journal_buckets() is called to check
whether there are enough free journal buckets to use. If there is only
1 free journal bucket and journal->do_reserve is 1 (true), the last
bucket is reserved and free_journal_buckets() will return 0 to indicate
no free journal bucket. Then journal_reclaim() will give up, and try
next time to see whetheer there is free journal bucket to allocate. By
this method, there is always 1 jouranl bucket reserved in run time.
During the cache set registration, journal->do_reserve is 0 (false), so
the reserved journal bucket can be used to avoid the no-space deadlock.

After making bch_sectors_dirty_init() being multithreaded, the existing
incremental dirty sector counting in bch_root_node_dirty_init() doesn't
release btree occupation after iterating 500000 (INIT_KEYS_EACH_TIME)
bkeys. Because a read lock is added on btree root node to prevent the
btree to be split during the dirty sectors counting, other I/O requester
has no chance to gain the write lock even restart bcache_btree().
That is to say, the incremental dirty sectors counting is incompatible
to the multhreaded bch_sectors_dirty_init(). We have to choose one and
drop another one.
In my testing, with 512 bytes random writes, I generate 1.2T dirty data
and a btree with 400K nodes. With single thread and incremental dirty
sectors counting, it takes 30+ minites to register the backing device.
And with multithreaded dirty sectors counting, the backing device
registration can be accomplished within 2 minutes.
The 30+ minutes V.S. 2- minutes difference makes me decide to keep
multithreaded bch_sectors_dirty_init() and drop the incremental dirty
sectors counting. This is what this patch does.
But INIT_KEYS_EACH_TIME is kept, in sectors_dirty_init_fn() the CPU
will be released by cond_resched() after every INIT_KEYS_EACH_TIME keys
iterated. This is to avoid the watchdog reports a bogus soft lockup
warning.

Commit b144e45fc576 ("bcache: make bch_sectors_dirty_init() to be
multithreaded") makes bch_sectors_dirty_init() to be much faster
when counting dirty sectors by iterating all dirty keys in the btree.
But it isn't in ideal shape yet, still can be improved.
This patch does the following changes to improve current parallel dirty
keys iteration on the btree,
- Add read lock to root node when multiple threads iterating the btree,
to prevent the root node gets split by I/Os from other registered
bcache devices.
- Remove local variable "char name[32]" and generate kernel thread name
string directly when calling kthread_run().
- Allocate "struct bch_dirty_init_state state" directly on stack and
avoid the unnecessary dynamic memory allocation for it.
- Decrease BCH_DIRTY_INIT_THRD_MAX from 64 to 12 which is enough indeed.
- Increase &state->started to count created kernel thread after it
succeeds to create.
- When wait for all dirty key counting threads to finish, use
wait_event() to replace wait_event_interruptible().
With the above changes, the code is more clear, and some potential error
conditions are avoided.

Commit 8e7102273f59 ("bcache: make bch_btree_check() to be
multithreaded") makes bch_btree_check() to be much faster when checking
all btree nodes during cache device registration. But it isn't in ideal
shap yet, still can be improved.
This patch does the following thing to improve current parallel btree
nodes check by multiple threads in bch_btree_check(),
- Add read lock to root node while checking all the btree nodes with
multiple threads. Although currently it is not mandatory but it is
good to have a read lock in code logic.
- Remove local variable 'char name[32]', and generate kernel thread name
string directly when calling kthread_run().
- Allocate local variable "struct btree_check_state check_state" on the
stack and avoid unnecessary dynamic memory allocation for it.
- Reduce BCH_BTR_CHKTHREAD_MAX from 64 to 12 which is enough indeed.
- Increase check_state->started to count created kernel thread after it
succeeds to create.
- When wait for all checking kernel threads to finish, use wait_event()
to replace wait_event_interruptible().
With this change, the code is more clear, and some potential error
conditions are avoided.

Pull AMD SEV-SNP support from Borislav Petkov:
"The third AMD confidential computing feature called Secure Nested
Paging.
Add to confidential guests the necessary memory integrity protection
against malicious hypervisor-based attacks like data replay, memory
remapping and others, thus achieving a stronger isolation from the
hypervisor.
At the core of the functionality is a new structure called a reverse
map table (RMP) with which the guest has a say in which pages get
assigned to it and gets notified when a page which it owns, gets
accessed/modified under the covers so that the guest can take an
appropriate action.
In addition, add support for the whole machinery needed to launch a
SNP guest, details of which is properly explained in each patch.
And last but not least, the series refactors and improves parts of the
previous SEV support so that the new code is accomodated properly and
not just bolted on"

Pull EDAC updates from Borislav Petkov:
- Switch ghes_edac to use the CPER error reporting routines and
simplify the code considerably this way
- Rip out the silly edac_align_ptr() contraption which was computing
the size of the private structures of each driver and thus allowing
for a one-shot memory allocation. This was clearly unnecessary and
confusing so switch to simple and boring kmalloc* calls.

Pull interrupt handling updates from Thomas Gleixner:
"Core code:
- Make the managed interrupts more robust by shutting them down in
the core code when the assigned affinity mask does not contain
online CPUs.
- Make the irq simulator chip work on RT
- A small set of cpumask and power manageent cleanups
Drivers:
- A set of changes which mark GPIO interrupt chips immutable to
prevent the GPIO subsystem from modifying it under the hood. This
provides the necessary infrastructure and converts a set of GPIO
and pinctrl drivers over.
- A set of changes to make the pseudo-NMI handling for GICv3 more
robust: a missing barrier and consistent handling of the priority
mask.
- Another set of GICv3 improvements and fixes, but nothing
outstanding
- The usual set of improvements and cleanups all over the place
- No new irqchip drivers and not even a new device tree binding!
